21 Claims.

This invention relates to textile machinery, more particularly to the control of the yarn as it is being packaged, and has for one of its objects the better control oi the yarn as it is being 5 directed to the package and the reduction of breaks, particularly as the package is nearing completion.

Another object of the invention is the provision of larger packages on the same gauge spinning frame without increasing the breakage of ends whereby dofiing is less frequent.

Another object of the invention is to relieve undue tension on the yarn as it is being packaged.

Another object of the invention is by means of a better control of the yarn to form better yarn from a drafting mechanism where the same is attenuated.

Another object of the invention is the obtaining of a greater movement of the thread guide board of a drafting frame.

Another object of the invention is the provision of a mechanism which may be attached to the means for oscillating the ring rail of a spinning frame to derive its movement therefrom and yet provide an independent operation of the thread board as to the amount of travel of the ring rail and a control thereof.

Another object of the invention is the control of the thread guide board of a drafting or spinning frame independently of the ring rail so that the thread guide board may be moved or remain stationary during any part of the operation of the ring rail, without interrupting or in any way affecting the movement of the ring rail.

A more specific object of the invention is to obtain. a greater movement of the thread guide board of a drafting'or spinning frame during a portion of the builder motion while stopping the movement of the thread guide board and main.- taining it in its highest position during the completion or finish of the builder motion in forming the package.

With these and other objects in View, the invention consists of certain novel features of con,- struction, as will be more fully described, and particularly pointed out in the appended claims.

In the use of spinning and drafting frames, the size of package which may be formed on the spindle is limited by certain factors entering into commercial production, such as by the closeness of the spindles one to the other or the gauge of the frame. 1f the spindles are too close together, the balloon of the yarn as the traveler moves along the ring of one spindle will interfere with the balloon of the yarn of the next spindle. The greater the distance between the ring rail and the thread board guide, the greater will be the balloon of the yarn; also, the length of the packages which are wound is limited as should the top of the package approach too closely to the thread board guide a tension will occur so great that the yarn will break. The commercial spinning frame is so arranged as to gauge and position of the thread board guide as to acquire the largest package with least breaks. By the use of this invention, a package containing substantially i'lfty percent more of yarn on a bobbin may be obtained than in the frames now in commercial use; and this is accomplished by the much larger and independent selective and controlled movement of the thread board guide than has ever heretofore been known.

The thread board guide is moved downwardly with the ring rail to control the ballooning and yet it is raised to its extreme height near the end of the winding of thread onto the package to relieve undue tension on the yarn as the top of the package is reached.

The heretofore commercial thread guide board has had a very short movement, possibly a quarter of an inch; and in order to overcome the difficulties Which exist in such a mechanism I have arranged a construction whereby the thread board may be moved any desired extent and f en through different amounts during the building of the yarn on the bobbin as I control the movement of the thread board by a cam, the `surface of which may be varied throughout a wide range; and as it is unnecessary that the thread guide board move during the latter half of the packaging, I move the thread guide board only during the firstpart of the building of the yarn on the package and stop it at the top of its movement during the latter part or at any desired point during its travel; thus, I control the ballooning where such ballooning is desired to be controlled as the yarn is wound on the package at the lower end while as the ballooning will not occur to as great an extent at the top of the package, the thread guide board may have its movement halted and yet be such a distance from the top of the package that no undue strain will be caused on the yarn. Thus, I provide a better yarn and may provide a package containing more thread and yet be obtained on a frame of a gauge which has a maximum size package of much lessi yarn; and the following is a more detailed description of the present embodiment of this invention, illusytrating the preferred means by which these advantageous results may be accomplished:

The spinning or drafting frame is largely of the usual type consisting of back to back sides of the frame, each side comprising a plurality of spindles, thread board guide, roll stand and rolls for drafting and supports for roving packages. My invention is applied to both sides of the frame with a common control between the parts for controlling the operation thereof.

With reference to the drawings, the back to back sides of the frame are substantially alike and the description of one will serve for both; I6 designates the common upright portion of the frame at one end and the horizontal xed angle iron beam supported therefrom, the upper flange i6 of which provides a spindle rail, while i2 is the fixed roll stand support also supported by the upright frame l0. A roll stand I3 suitably supports pairs of draft rolls designated generally I4 which receive roving from the supply packages l5 to attenuate the same and deliver each end down through the pigtail guide Vil supported by the thread 'guide board |8, thence downwardly under the traveler I9 on the ring 20 supported by the ring rail 2| from whence the thread designated 22 is delivered to the bobbin 23 supported on the spindle 24 and rotatably iuiounted in the spindle rail |6 and suitably driven 'by a belt from the large drum as is usual in constructions of this character. The draft rolls are driven by suitable gearing housed within the guard 25 at one end of the frame.

This ring rail 2| is supported by rods 38 at spaced intervals along the frame, which rods are slidably mounted in the flange |6 and the flange 3| of the beam and are movable relatively thereto for the traverse motion of the rail along 'the bobbin.

The rods 36 are each provided with an enlarged abutment surface 32 formed by the flat flanged end of a collar 33 which is secured to the end of the rod 33. Each abutment surface 32 rests upon the anti-friction roller 34 adjustably supported at the end 35 of a bellcrank lever 36, several of which are pivoted about shafts 31 positioned along'the frame on brackets 40 bolted as at 4| to the beam and extending across from one side to the other of the frame where the shafts are similarly supported and serve to mount similar l bellcrank levers at vthe head end of the frame.

The bellcrank levers 36 on opposite sides are fixed to the shaft 31 in the brackets 46 to transmit motion through shaft 31 from one side of the machine to the other that the bell crank levers 36', 36' on both sides of the frame will operate by applying operating movement to one alone. The arms 38 of the bellcrank levers 36 are all connected together and to the arm 43 of the lever 36 by a suitable coupling rod 39 so as to cause all of the bellcrank levers on one side of the machine to operate in unison and uniformly raise the ring rail at all of its spaced supporting points.

The bellcrank lever 36' at the head end of the machine has its arms 43 shaped dierently from the arms 38 of the other bellcrank levers along the side of the frame. The arm 43 is provided with an arcuate end portion 44 on an arc struck from the center of the shaft 31 to which arm coupling 45 of the rod 39 is pivoted as at 46. While it is provided with a lug 41 for receiving a connecting bolt 48 for tieing a flexible connection such as the chain 49 thereto, the bolt being secured in position by a nut 5D on the threaded shank 5| thereof, and through this chain an oscillating motion is provided for all of the bellcrank levers of the frame.

The pick motion is derived by means of a cam 5| mounted on shaft 52 which is driven by a bevel gear 53 from the bevel pinion 54 mounted on shaft 55 and suitably driven by gear 56 from some source of power. A lever 51 pivoted at 58 is urged by means of the cam 5| engaging antifriction roller 59 supported thereon to cause the lever 51 to be reciprocated. This lever has oertain take-up mechanism mounted at the end thereof including a drum 69 to which the chain 4,9 is connected so that as the lever moves it bodily moves the drum 60 which pulls the chain 49 over the pulley 6| to swing the levers 36', 36 about their pivot and lift the rods 3|) and in turn the ring rail. The weight of the ring rail serves to impart movement of the lever 36', 36 in the opposite direction to keep the chain 49 taut and the roll 59 against the cam 5|.

The above serves to give a reciprocating motion to the ring rail but in order to cause the ring rail to advance along the package the drum 60 is gradually rotated automatically by a shaft 62 mounted in suitable bearings in the U-shape portion 63 of the lever 51. This shaft extends through slot 64 in the bracket 65 which is suitably mounted by means of a bolt 66 on the beam so that as the lever 51 moves up and down this shaft 62 will move up and down in the slot 64 in the bracket. A ratchet Wheel 61 is fixed on the end of the shaft 62 While a slotted arm 68 is loosely mounted on the shaft 62 and has a pawl 69 for engaging with the teeth of the ratchet wheel 61.

The arm 68 is guided in its movements by a pin carried by the end of an arm 1| which extends through a slot 12 in the bracket 65 and may be held in different adjusted positions by means of a bolt 13 which extends through a slot 14 also in the bracket 65. Thus, the position of the pin 10 may be determined for varying the throw of the pawl 69 and the relative rotation of the ratchet wheel 61 which will be caused by reciprocating movement of shaft-62 and the arm 68 thereon so as to rotate the ratchet Wheel 61 and the shaft 62.

The drum 60 is loosely rotatably mounted upon the shaft 62and has secured to it a gear 15 which may be integral therewith. This drum is rotated by means of the train of gears 16, 11, fixed on shaft 18 and a gear 19 fixed on shaft 62 by reason of which avery slow but positive rotation is given .to the drum 69 to gradually wind up the chain 49 to cause the traverse of the ring rail to move upwardly along the bobbin.

The thread board guide |8 is supported by a plurality of rods 85 extending downwardly and suitably guided through the spaced eyes 86 mounted onthe bracket 81 secured to the roll standsupport I2. A roller 88 is adjustably secured to` each rod 85 and rests upon a movable controlling member 99 which I have formed in the desired shape to govern-the movement of the thread board guide which I here show as an inclined surface 9| of a predetermined desired pitch and length. Each of thesemembers 90 is the same and are positioned the same with reference to thel red 85 while all are connected together byasuitable thrust transmitting connection 92, whereby I may move' all of these control members 90 together or in unison. The weight of the thread guideV board I8 and its supporting rods is sufficient when resting upon the incline 9| to move this member to the right as viewed in Figs. 1 and 2; and in order to move these members 99 in the other direction or toward' the left in these gures I attach to some reciprocating part of the mechanism of the machine which will exert a pull in the required direction at the desired interval and for this purpose I here attach a flexible connectionV 93 to the aforementioned chain 49 which imparts motion to the ring rail mechanism through which chain 93 a movement is periodically transmitted to the members 99 to the left in Fig.k 1. In this particular showing a drum 94 is secured to shaft 95 supported in brackets 99 on opposite sides of the frame about which drum the chain 9-3 is partially wrapped and secured. On shaft 95- a pulley 91 is secured from which a chain 98 leads to bracket 99 secured tothe member 99. Connection is alsol madeto the other side of this bracket that the members 99 may be morey readily returned toy starting position by meansl of chain |09 extendthrough shaft 95 as shown in Fig. 3.

It -wi-ll, of course, be'apparent that as the reciprocation of the ring rail takes place the drum G9 is being ratcheted around so as to cause the ring railvto Ycontinually rise, that is,r it will never come quitel down to where it did the previous reciprocation and will each time go up just a little: higher, although the length of traverse will be the same. Likewise, the chain 93 moving with chain 49 intermittently pulls the support 99 with its inclined surface 9| so that at the beginning of operation when the roll 88 is at the bottom of the incline 9| a pull on the member 99 Will raise the roll 88 upwardly along the incline 9| and when the pull toward the left, Fig. 1, ceases and the lever 5-1 lifts the weight of the thread board will move the member 99 in the other direction, keeping the chain 93 tight. Gradually, however,

as the chain 49 winds on the drum 69 the cams- 9'9 will be drawn tothe left and the roll 88 will travel higher and higher on the incline 9| until it reaches the flat surface as shown in Fig. 1 so that the thread board guide wil-l no longer reciprocate. Thus, by this arrangement I may control the thread board through any desired shape of surface cam 9| so that the desired movement maybe obtained and all this independently of the Vmovement of the rail, although I obtain my movement from the mechanism which operates the ring rail.

I may extend these inclined surfaces of the cams 9| to any extent and I may cause them to be sufficiently steep to obtain the desired reciprocation of the thread board guide. In the present instance, I have so arranged the cams that the thread board guide will operate about threequarters of an inch, although the range of reciprocation is from a quarter of an inch to an inch and a quarter. The ring rail operates yor lifts an inch and Ve-eighths which is more or less standard. The inclined surface 9| is of such an incline and so positioned that the thread board guide will operate through this threefourths of an inch, while the thread is being packaged on the lower part of the bobbin, however, When the rail reaches a point so that the bobbin is substantially half full the horizontal surface of the cam will then be carrying the roll 88 and from this point on the thread board guide will remain at the top of the stroke and no longer reciprocate.

After the bobbins are full and it is necessary to doi, the pulley 6| which is mounted upon a segment |99, pivoted as at |91 and having a toothed rack |09 which is engaged by a pinion |99, is lowered by turning the squared end of shaft ||0 by a crank so as to thereby drop the ring rail to its lowermost position; also, a crank is applied to the squared end of the shaft 62 and by disengaging pawl 69, I unwind from the drum the chain 49 returning it to starting position. Also, a crank is applied to the squared end H4 of the shaft 95 and by turning in the proper direction the chain |09 draws the control members 99 back to their starting positions with the roll 99 resting upon the incline 9| at the lower portion thereof, it being more desirable to manually return the controlmembers 99 to starting positions than to apply some spring or weight means which would require too great a force and drag upon the mechanism while it was reciprocating back and forth during the working transverse of the thread board guide.
